Title:
メディアストリーミングのための伝送帯域幅測定システム及びその方法
Document Type and Number:
Japanese Patent JP5422654
Kind Code:
B2
Abstract:
The present invention relates to a system for measuring a transmission bandwidth that calculates a transmission bandwidth not by transmitting a proving packet to the receiving side, but rather by using a transmission packet to be transmitted to a receiving side, and streams multimedia data to the receiving side by using the transmission bandwidth, in a service for streaming multimedia data on a real-time basis, and to a method for same. The system for measuring a transmission bandwidth according to the present invention, includes: a server for transmitting packets of multimedia data to a receiving apparatus, receiving received time stamp on the reception of packets from the receiving apparatus, calculating a transmission bandwidth from the received time stamp, and streaming the multimedia data to the receiving apparatus in accordance with the calculated transmission bandwidth; and a receiving apparatus for receiving packets of the multimedia data from the server, recording received time stamp for each of received packets, and transmitting the received time stamp to the server by a predetermined cycle. According to the present invention, transmission bandwidth can be measured not by using a proving packet, but rather by using data to be actually transmitted. Moreover, additional occupation of the transmission bandwidth due to a proving packet can be prevented, and multimedia data streaming suited to a transmission bandwidth can be efficiently performed. Further, streaming of media suiting to a transmission bandwidth meets QoS (Quality of Service) requirements.
